PAGE-INDICATOR.

SPECIFICATION forming part of Letters Patent No. 680,363, dated August13, 1901.

Application filed December 1, 1900. Serial No. 38,852. No model.)

To all whom, it mag/concern:

Be it known that I, ROBERT SCOTT, a citizen of the United States,residing at North Yakima, in the county of Yakima, State of Washington,have invented certain new and useful Improvements in Page-Indicators;and I do hereby declare the followingto be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to indicators in general, and more particularlyto those designed to be used in connection with books, and has for itsobject to provide a device of this natu re which will retain the book inan open position, which will keep the column heading or title directlyabove the line to be written upon, and which will be cheap ofmanufacture and simple of construct-ion.

In the drawings forminga part of this specification, in which likecharacters of reference indicate similar parts in the several views,Figure 1 is a top plan view of a book provided with my invention. Fig. 2is a section on line 2 2 of Fig. 1, and Fig. 3 is a section on line 3 3of Fig. 1.

In the construction of a column-indicator in accordance with myinvention I provide two plates 5, preferably of sheet metal, which aresubstantially in the shape of a truncated rightangle triangle, and theseplates are hingedly connected at their broad ends. As shown in Fig. 2,each of the plates 5 is curved downwardly at the ends I) and b toconform to the shape of the book.

Secured to the upper faces of plates 5 are strips 6 of lead or otherheavy metal, which are substantially semicircular in cross-section, theobject of these strips being to add the necessary weight to the deviceto cause the pages of the book to lie fiat. Each of these strips 6 isprovided along its edge 6 with a slit 7, into which is inserted a secondmetal plate 8, as shown in Fig. 3 of the drawings. The lower face 8 ofthe plate 8 is brought into contact with the upper face of plate 5 bybein g curved downwardly over the rounded surface 6 of the strip 6, thetwo plates forming a spring-clip, into which may be inserted a strip ofpaper 12, on which the column-head ings are written or printed. 'i

Secured to the under face of each of the plates 5 are clips 10, whichhold astrip of Not ting-paper 20 of the same size and shape as the plateitself, and this strip of blotting-pa per will absorb the ink as thedevice is moved downwardly over the portion of the page already writtenupon.

In practice the indicator is placed upon an open book, the hinge restingin the fold of the pages and the downwardly-turned ends I) lying againstthe edges thereof. The strip of paper 12 is divided into spaces of thesame width as the columns of the book, and when the device is inoperative position these spaces should form a part of the columns, asshown in the drawings. After one line of the book is written upon theindicator is moved downwardly to cover this line, and the edge of strip12 should then be on a line with the upper boundary of the space next tobe written upon. In this manner the column-headings are kept at alltimes directly under the eye of the writer, obviating the necessity ofglancing at the top of the page.

YVhat is claimed is 1. A device of the class described comprising hingedplates having clips at the front and rear edges on the under sidesthereof adapted to receive a blotter, and clips upon the upper faces ofthe plates at the front edges thereof to receive slips of headings.

2. A device of the class described comprising weighted hinged plates,said plates having each a blotter secured to its under side and havingclips on its upper side for engagement with heading-slips.

3. A device of the class described comprising hinged plates, a weightsecured to the upper face of each plate, spring-clips engaged in theweights and disposed to exert clamping actions against the plates, andmeans for holding blotters to the under sides of the plates.

In testimony whereof I hereunto sign my name, in the presence of twosubscribing wit- 5 nesses, on the 16th day of October, 1900.

ROBERT SCOTT.
